And also could you tell my why I had to click 'inject' instead of 'inject folder' since when I injected the correct folder, the Xtaf Xplorer crashed. I had to inject each file in the folder bit by bit, and put it into one folder named '000001.'

How will the latest file work with my existing save games? I have the 2nd latest DLC installed with Daymos V2 option file. Didn't want to bring in the new one if it might corrupt my Master League with OPE FC.

I remember someone did just that in PES2010 and the Xbox or game couldnt cope with the conflicting amounts of data..

Ive tried it this timein PES2012 and believe it or not I was playing my masterleague just this weekend using the old Henry in my Arsenal team but in the main game the old (created) Henry is nowhere to be seen only the correct (Konami) Henry.

So to answer part of your question.. you can update but your ML will remain the same.. no players or transfers or stats will change within your ML but only in your main game with all the game modes will you see the new transfers in v3.

I've got a problem ,i have not connection to XBL and have no JTAG, my PES 2012 has no pacht or any option file, i put only Daymos OF v3 immeadietely on hdd and when it loads screen shows this : "[edit data] Unable to load because data is for diffrent version. Download new contents to update data." what to do???

Guess I'll just have to either inject the folder bit by bit into 3 parts, (then copy each part file separately onto the 360) or live with it. Probably just live with it and wait until the next option file. Thanks Daymos.
